...5y+3z = -10 Go to your matrix button and enter a "3x4" matrix. Then enter it as follows: -3 4 5 7 4 3 2 9 -5 5 3 -10 Then exit out and go to "2nd->matrix->math->rref(". Then press enter. Your screen ...

4x+8y=20 -4x+2y=-30 4x+8y=20 || /4 x+2y=5 x=5-2y -4x+2y=-30 || /2 -2x+y=-15 -2(5-2y)+y=-15 -10+4y+y=-15 5y=-5 y=-1 x=5-2y || y=-1 x=5-2(-1) x=5+2 x=7

10 becomes -5y = 30 (subtract 1y from each side and add 20 to each side) becomes y = -6 (div by -5) now you know what y is, plug it back into one of the original equations to find x x = -2 y = -6 note

10 y-intercept (initial value) Set x= 0 in the equation and solve for y: 2(0)-5y=20 and y=20/(-5)=-4 If the equation is in the slope-intercept form y=ax+b 1. y-intercept is b 2. To get the x-intercept

5Y=3Y+8 2Y=8 Y=4 I hope that helps. Joe. Let m be Tom's age and d be Todd's age. Nowm = 5 x d In seven years m + 7 = (d + 7) x 3 + 6 By substituting m 5 x d + 7= (d + 7) x 3 + 6 By simplifying

...5y-25=0.Check the calculation by verifying that the point (10,7) lies on the line.6(10)-5(7)-25=60-35-25=60-60=0 CHECKed!Check that the second point (-5,-11) lies on the line also (if you want ...

...the x-value to 0 in the equation of the line. 50+25x-5y=0 50+25(0)-5y=0, or 50-5y=0. The solution is y=50/5=10 The straight line cuts the x-axis at the point (-2, 0) and the y-axis at the point
