Answer:
x = - 10
Step-by-step explanation:
Given
5x + 3 = 4x - 7 ( subtract 4x from both sides )
x + 3 = - 7 ( subtract 3 from both sides )
5x+3=4x-7
Move 3 to the other side
Sign changes from +3 to -3
5x+3-3= 4x-7-3
5x= 4x-10
Move +4x to the other side
Sign changes from +4x to -4x
5x-4x= -10
1x= -10
Divide by 1
1/1x= -10/1
x= -10
Answer : x= -10
