Answer:

[tex]\boxed{\bold{x=5}}[/tex]

Step By Step Explanation:

Multiply Both Sides By 4:

[tex]\bold{\frac{4\left(5x+3\right)}{4}=7\cdot \:4}[/tex]

Simplify:

[tex]\bold{5x+3=28}[/tex]

Subtract 3 From Both Sides:

[tex]\bold{5x+3-3=28-3}[/tex]

Simplify:

[tex]\bold{5x=25}[/tex]

Divide Both Sides By 5:

[tex]\bold{\frac{5x}{5}=\frac{25}{5}}[/tex]

Simplify:

[tex]\bold{x=5}[/tex]

Answer:

x = 5

Step-by-step explanation:

to solve, we want to get x by itself on the left hand side. to do this, we do the opposite operation to a number, such as multiplying by 4 in order to get rid of the dividing by 4

step 1: we will multiply both sides of the equation by 4 to get rid of the 4 in the denominator

5x + 3 ÷ 4 = 7

× 4              × 4

the 4s cancel on the left and we are left with:

5x + 3 = 28

step 2: subtract 3 from both sides to get 5x alone

5x + 3 = 28

-3.         -3

5x = 25

step 3: divide both sides by 5 to get x alone

5x/5 = x

25/5 = 5

x = 5 is our answer, you can plug in the value into the original equation to check, but it is not necessary
