3X + 2X - 10 = 200
|
COMBINE LIKE TERMS: 3X + 2X = 5X AND 200 - 10 = 190 SINCE YOU HAD TO MOVE ACROSS THE STREET OR SIGN SO 5X = 190 YOU DIVIDE BOTH SIDES BY 5 AND X = 38
|
|
|
1/3 X + 21 = 50
|
ISOLATE THE VARIABLE BY MOVING 21 TO THE OTHER SIDE OF THE ROAD TO MAKE IT A NEGATIVE 21 SO 50 - 21 = 29 THEN MULTIPLY BOTH SIDES BY THE INVERSE OR UPSIDE DOWN OF 1/3 WHICH IS 3/1 TO GET X = 3/1 X 29/1 AND YOU GET X = 87
|
|
|
X - 38 = 12
|
ISOLATE THE VARIABLE X BY MOVING NEGATIVE 38 ACROSS THE ROAD OR SIGN TO MAKE IT A POSITVE 38. Then 12 + 38 = 50 x = 50
|
|
|
27x + 1 = 55
|
isolate the variable by moving positive 1 across the road sign making it a negative 1 THEN 55- 1 = 27x THEN 54 = 27 x THEN divide both sides by 27 x = 2
