-7x + 4y = -6
2x - 5y= 21
<u>Make it so x's are equal</u>
-14x + 8y = -12
-14x - 40y = 147
<u>Subtract</u>
-32y = -169
<u>Divide</u>
y = 5.28125
<u>Plug in the y value</u>
2x - 5(5.28125) = 21
<u>Simplify</u>
2x -26.40625 = 21
<u>Add</u>
2x = 47.40625
<u>Divide</u>
x = 23.703125
Hope this helps! ;)
