Answer:
2
Step-by-step explanation:
5(2x+3)+3x=4(x+7)+5
We move all terms to the left:
5(2x+3)+3x-(4(x+7)+5)=0
We add all the numbers together, and all the variables
3x+5(2x+3)-(4(x+7)+5)=0
We multiply parentheses
3x+10x-(4(x+7)+5)+15=0
We calculate terms in parentheses: -(4(x+7)+5), so:
4(x+7)+5
We multiply parentheses
4x+28+5
We add all the numbers together, and all the variables
4x+33
Back to the equation:
-(4x+33)
We add all the numbers together, and all the variables
13x-(4x+33)+15=0
We get rid of parentheses
13x-4x-33+15=0
We add all the numbers together, and all the variables
9x-18=0
We move all terms containing x to the left, all other terms to the right
9x=18
x=18/9
x=2
Answer:
Step-by step explannation
10x+15+3x=4x+28+5
10x+3x+15=4x+28+5
13x+15=4x+33
13x-4x=33-15
9x=18
x=2
