Answer:
[tex]y=14[/tex] , [tex]x=-2[/tex]
Step-by-step explanation:
If two items or expressions are equal to the same subject then they are equal to each other,
y = 4x + 22 and y = -7x
Using the statement at the top
[tex]4x + 22 = -7x[/tex]
Subtract -7x from both sides to collect the x terms
[tex]11x+22=0[/tex]
Minus 22 from both sides to isolate 11x
[tex]11x=-22[/tex]
Divide both sides by 11 to isolate x
[tex]x = -2[/tex]
Now that we have the value of x we can substitute it into any of the equations to find the value of y
Substitute x = -2 into y = -7x
[tex]y = 14[/tex]
So the solution is [tex]y=14[/tex] and [tex]x=-2[/tex]
Hope this helps :)
