Answer:
A
Step-by-step explanation:
since both equations express y in terms of x we can equate the right sides
x + 7 = - 2x + 19 ( add 2x to both sides )
3x + 7 = 19 ( subtract 7 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
substitute x = 4 into either of the 2 equations for y
y = x + 7 ⇒ y = 4 + 7 = 11
solution is (4, 11 )
A is the answer
The answer is 7
yes
1.-3
2.3
3.10
4.2
5.3
X= -14
So we can first simplify the equation
2x+10=x-4
Now just solve i normally
x+10=-4
x=-14
So x is -14
