SECTION 2-4 : SOLVING EQUATIONS WITH THE VARIABLE ON BOTH SIDES

2. *Variable on one side, constant on the other.
*-But, you know that.

3. Solve each equation. Check your answer.
1) 5s + 13 = 2s + 22
3) 2(3x + 1) = 4(x – 5)
ANSWER : 3
ANSWER : -11
4) -8(-2a + 5) = 13 – 3(5a – 3)
2) y + 7 = 9y - 1
ANSWER : 1
ANSWER : 2

4. 7) t + 8 = -(t – 6) + 2t 6) 5(x + 4) = x + 2(x + 3)
ANSWER : no solutions
ANSWER : -6
6) 5(x + 4) = x + 2(x + 3)
8) 8m + 2 = 2 – 3m + 11m
ANSWER : -7
ANSWER : identity

5. If you are working an equation and the variable disappears, and the result is a ….
true statement (0=0, 2=2, 10=10, etc.), the equation is an identity – all numbers work, or a
false statement (0=3, -7=0, 3=4), the equation has no solutions

6. 9)
ANSWER : 1
10) -5(3x + 4) + 13x = 2(x – 5)
ANSWER : no solutions
