The value of the solution of expression is, x = 11
We have to give that,
An expression to simplify,
4x - 7 = 2x + 15
Now, Simplify the expression by combining like terms as,
4x - 7 = 2x + 15
Subtract 2x on both sides,
4x - 2x - 7 = 15
2x - 7 = 15
Add 7 on both sides,
2x - 7 + 7 = 15 + 7
2x = 22
Divide 2 into both sides,
x= 22/2
x = 11
Therefore, the solution is, x = 11

Choose 3 answers:
A) 13 = 9 + m
B)7- m = 3
C) 15 = 11m
D) 5 = m + 2
E) 20 divide m =5
Answer:
A, B, E
Step-by-step explanation:
A) 13=9+m
m= 13-9
m=4 ✔️
B) 7-m =3
m= 7-3
m=4 ✔️
C) 15= 11m
15=11*4
15≠44
D) 5= m+2
If m=4 therefore
5≠4+2
5≠6
E) 20 divide m = 5
20/4 = 5
therefore, m=4 ✔️
By substituting m=4 into each equation, we find that options A) 13 = 9 + m and E) 20 divided by m = 5 are the correct equations where m=4 is a solution.
In mathematics, specifically algebra, we can solve and check equations by plugging in values. You are asked to find the equations where m = 4 is a solution.
Let's substitute m with 4 in each equation:
Therefore, the equations where m=4 is a solution are A) 13 = 9 + m and E) 20 divided by m = 5.
