Rearrange:

Reararray the equation by subtracting what is to the right of the equal authorize from both sides of the equation : 4*(5*n-7)-(10*n+2)=0

Tip by step solution :

Tip 1 :

Equation at the finish of step 1 :

4 • (5n - 7) - (10n + 2) = 0

Step 2 :

Tip 3 :

Pulling out choose terms :3.1 Pull out favor factors:10n - 30=10•(n - 3)

Equation at the finish of action 3 :

10 • (n - 3) = 0

Tip 4 :

Equations which are never before true:4.1Solve:10=0This equation has no solution. A a non-zero consistent never before amounts to zero.

Solving a Single Variable Equation:4.2Solve:n-3 = 0Add 3 to both sides of the equation:n = 3

One solution was discovered :

n = 3




You are watching: 4(5n-7)=10n+2
