Answer:
All real numbers
Step-by-step explanation:
There is 3 possible solutions to a linear equation:
- One solution -a unique x value that makes the equation true
- No solution - a false statement is given after solving without a value for x
- Infinite solution - a true statement is given after solving without a value for x
Solve using inverse operations:
4(a+2)=14-2(3-2a)
4a+8=14-6+4a
4a-4a+8=8+4a-4a
8=8
Is 8=8? Yes. Therefore this is a true statement with no value for x. Infinite solutions or all real numbers.
Answer:
X=-4, y=-7
Step-by-step explanation:
6x-5y=11. 1st equation
y=7x+21 2nd equation
6x-5(7x+21)=11. Sub value of y in 2nd equation (7x+22) into 1st equation
6x-35x-105=11. Solve by distributative property
-29x-105=11. Add x values
-29x=116. add 105 to both sides
x=-4. Solve for x
solve for y:
y=7x+21
y=7(-4)+21
y=-28+21
y=-7
check answer by substituting x and y into either equation
6x-5y=11
6(-4)-5(-7)=11
-24+35=11
11=11
