Y = -2x +7
y = 5-7
Find the solution to the system of equations

y = 5 - 7

=> y = -2 (i)

y = -2x + 7

=> -2 = -2x + 7 [From (i)]

=> -2 -7 = -2x

=> -9 = -2x

=> -9/-2 = x

=> 9/2 = x

So, x = 9/2 and y = -2

add 5)5(5 to both sides

6x=4+56x=4+56x=4+5

simplify 4+54+54+5 to 999

6x=96x=96x=9

divide both sides by 666

x=96x=\frac{9}{6}x=​6​​9​​

simplify 96\frac{9}{6}​6​​9​​ to 32\frac{3}{2}​2​​3​​

x=32x=\frac{3}{2}x=​2​​3​​
