Respuesta :
x=2 5x plus 2x is 7x then you subtract the 4 to the 18 and get 14, then divide the 7x from the 14 to get 2x
Answer:
x=2
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+2x+4=18
Step 1: Simplify both sides of the equation.
5x+2x+4=18
(5x+2x)+(4)=18(Combine Like Terms)
7x+4=18
7x+4=18
Step 2: Subtract 4 from both sides.
7x+4−4=18−4
7x=14
Step 3: Divide both sides by 7.
7x /7 = 14/ 7
x=2
