15 - x = 2(x + 3)
15 - x = 2x + 6
15 = 3x + 6
9 = 3x
3 = x
x = 3
Answer:
y = - 10
Step-by-step explanation:
Given
y - 3 = - 3y - 43 ( add 3y to both sides )
4y - 3 = - 43 ( add 3 to both sides )
4y = - 40 ( divide both sides by 4 )
y = - 10
Twice the value of x is 2x, because it’s x with another x added on top (x + x = 2x)
Eight less than that is 2x - 8. That’s because you are taking away 8 from 2x (less than = subtraction).
Therefore your final expression is 2x - 8.
Answer:
The expressions are equivalent
Step-by-step explanation:
5(2x+3)
Distribute the 5
5*2x + 5*3
10x +15
That is equal to 10x+15
The expressions are equivalent
1 and one fourths( 1 1/4)
