1. −2
2. −4
3. −10
4. −14
2 answers:
4(x + 2) = 3(x − 2)
Mutiply the first bracket by 4
(4)(x)(4)(2)= 4x+8
Mutiply the second bracket by 3
(3)(x)(3)(-2)= 3x-6
4x+8= 3x-6
Move 3x to the other side
Sign changes from +3x to -3x
4x-3x+8= 3x-3x-6
4x-3x+8= -6
x+8= -6
Move +8 to the other side
Sign changes from +8 to -8
x+8-8= -6-8
x= -14
Answer: x= -14

You can formulate the equation below to work out your question:
3(2.99) + 1.99(x-3)
8.97 + 1.99x - 5.97
1.99x + 3
CHECK:
If x = 5
3 x 2.99 + 2 x 1.99 = 8.97 + 3.98 = 12.95
1.99 x 5 +3 = 12.95
