−7x + 25 = 48 Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23 Step 3: negative seven times x over seven = twenty-three over seven Step 4: x = twenty-three over seven Step 1: He should have added 25 to each side. Step 1: He should have divided both sides by −7. Step 3: He should have divided both sides by −7. Step 3: He should have multiplied both sides by −7.

Step 3: He should have divided both sides by −7

Step-by-step explanation:

Incorrect calculation

−7x + 25 = 48

Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23

Step 3: negative seven times x over seven = twenty-three over seven

-7*x/7 = 23/7

-7x/7 = 23/7

Step 4: x = twenty-three over seven

Correct calculation

−7x + 25 = 48

Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23

Step 3: negative seven times x over seven = twenty-three over seven

-7*x/-7 = 23/-7

-7x/-7 = 23/-7

Step 4: x = twenty-three over negative seven

x = -23/7

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
