Four times the sum of r and ten is equal to 4.

4(r+10) = 4

Step-by-step explanation:

4 (r+10) = 4

r = -9

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(r+10)=4

(4)(r)+(4)(10)=4(Distribute)

4r+40=4

Step 2: Subtract 40 from both sides.

4r+40−40=4−40

4r=−36

Step 3: Divide both sides by 4.

4r/4 = −36/4

r=-9

correct answer is infinitely many solutions

step-by-step explanation:

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

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

70,000 + 6,000 + 800 + 30
