Answer:
x=30
Step-by-step explanation:
To solve this equation, simplify using the distributive property and combining like terms. Then solve for x through inverse operations.
3x-2(x+4)=22
3x-2x-8=22
x-8=22
x-8+8=22+8
x=30
Answer:
a = 18
Step-by-step explanation:
2(a-7)=a+4
Distribute 2 into left side: 2a -14 = a + 4
subtract a from both sides 2a-a-14 = a+4-a
Simplify: a - 14 = 4
Add 14 to both sides: a - 14 + 14 = 4 +14
Simplify: a = 18
If wanted, plug a into original to double check work:
plug in: 2 (18-7) = 18+4
do parenthesis first: 2 (11) = 18+4
do multiplication : 22 = 18+4
additions: 22 =22
a = 18 is correct.
