Answer:
1. No solution
2. Infinite solutions
Step-by-step explanation:
1. To solve the system, set the equations equal to each other and solve for x.
2x - 5 = 2x + 7
-5 = 7
This is a false statement. This means there is no solution.
2. To solve the system, graph each equation.
y = -3/4 x - 5/2 has a y-intercept -5/2 and slope -3/4.
3x + 4y = -10 converts to y = -3/4x -5/2.
This graphs as the exact same line. This system has infinite solutions.
Answer:
x=10^{\frac{2}{3}}-5
Step-by-step explanation:
X = 114.
If you look, the angles are the same, therefore, 114.

Step-by-step explanation:
<u>Step 1: Define</u>
2(x/4 + 8) = 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide 2 on both sides: x/4 + 8 = 9
- Subtract 8 on both sides: x/4 = 1
- Multiply 4 on both sides: x = 4
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 2(4/4 + 8) = 18
- (Parenthesis) Divide: 2(1 + 8) = 18
- (Parenthesis) Add: 2(9) = 18
- Multiply: 18 = 18
Here we see that 18 does indeed equal 18.
∴ x = 4 is the solution to the equation.
