Combine multiplied terms into a single fraction

0.025(+2)=2.81

0.025(q+2)=2.810.025(q+2)=2.81

1(+2)40=2.81

\frac{1(q+2)}{40}=2.81401(q+2)=2.81

(2)

Multiply by 1

1(+2)40=2.81

\frac{1(q+2)}{40}=2.81401(q+2)=2.81

+240=2.81

\frac{q+2}{40}=2.8140q+2=2.81

Multiply all terms by the same value to eliminate fraction denominators

+240=2.81

\frac{q+2}{40}=2.8140q+2=2.81

40(+240)=40⋅2.81

40(\frac{q+2}{40})=40 \cdot 2.8140(40q+2)=40⋅2.81

Cancel multiplied terms that are in the denominator

40(+240)=40⋅2.81

40(\frac{q+2}{40})=40 \cdot 2.8140(40q+2)=40⋅2.81

+2=40⋅2.81

q+2=40 \cdot 2.81q+2=40⋅2.81

Multiply the numbers

+2=40⋅2.81

q+2={\color{#c92786}{40}} \cdot {\color{#c92786}{2.81}}q+2=40⋅2.81

+2=112.4

q+2={\color{#c92786}{112.4}}q+2=112.4

Subtract

 from both sides of the equation

+2=112.4

q+2=112.4q+2=112.4

+2−2=112.4−2

q+2{\color{#c92786}{-2}}=112.4{\color{#c92786}{-2}}q+2−2=112.4−2
