Answer:

x = 5

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

Answer:


\boxed{\bold{x=5}}

Step By Step Explanation:

Multiply Both Sides By 4:


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

Simplify:


\bold{5x+3=28}

Subtract 3 From Both Sides:


\bold{5x+3-3=28-3}

Simplify:


\bold{5x=25}

Divide Both Sides By 5:


\bold{(5x)/(5)=(25)/(5)}

Simplify:


\bold{x=5}
