What's the answer to 5x-4+2x=3

x = 1

Step-by-step explanation:

to evaluate for the value of x we would in the expression

5x-4+2x=3

we will collect the like terms

5x + 2x - 4 = 3

7x - 4 = 3

7x = 3 + 4

7x = 7

divide both sides by the coefficient of x which is 7

7x/7 = 7/7

x = 1

to check if your answer is correct you will put the value of x = - 1 into the expression 5x - 4 + 2x = 3 and see if the left handside is equal to the right handside.

5 (1) - 4 + 2 (1) = 3

5 - 4 + 2 = 3

1 + 2 = 3 ... proved

x = 1
