Answer:
Step-by-step explanation:
I’m not too good with this but the answer should be 87.5
2
x * 2x = 3x X*-8= -8x
minus 3x on both side
= -11x
-11x = 0
divide -11 on both side
= 0
Is this what you mean this is what i understood.
X-4=10;4x+1=57
First equation solve for x.
X-4=10
Add 4 both sides
X=10+4
X=14
Second equation substitute your x answer into second equation to make both sides equal.
4x+1=57
4(14)+1=57
56+1=57
57=57
