Hello!
You can solve this algebraically
-15 = 22x + 7
Subtract 7 from both sides
-22 = 22x
Divide both sides by 22
-1 = x
The answer is A) x = -1
Hope this helps!
162 is the answer i keep getting when i do it
Answer:
There is no solution for either variable without further information, as there are two variables given, but only one relationship between them.
You could however use them as a description of a line, which gives every possible solution.
35x - 7y = 49
7y = 35x - 49
y = 5x - 7
We now have an expression describing a line with a slope of five, which crosses the y axis at (0, -7) and the x axis at (1.4, 0)
Answer:
x = 21
Step-by-step explanation:
Step 1: Write out equation
-5x - 72 = -12x + 75
Step 2: Add 5x to both sides
-72 = -7x + 75
Step 3: Subtract 75 on both sides
-147 = -7x
Step 4: Divide both sides by -7
21 = x
Step 5: Rewrite
x = 21
Answer:
-37
Step-by-step explanation:
Simplifying
74 + 2x = 0
Solving
74 + 2x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-74' to each side of the equation.
74 + -74 + 2x = 0 + -74
Combine like terms: 74 + -74 = 0
0 + 2x = 0 + -74
2x = 0 + -74
Combine like terms: 0 + -74 = -74
2x = -74
Divide each side by '2'.
x = -37
Simplifying
x = -37
