Answer:
y = -1
Step-by-step explanation:
((3 • (5y + 2)) - y) - 2 • (y - 3) = 0
Step 2 :
Equation at the end of step 2 :
(3 • (5y + 2) - y) - 2 • (y - 3) = 0
Step 3 :
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
12y + 12 = 12 • (y + 1)
Equation at the end of step 4 :
12 • (y + 1) = 0
Step 5 :
Equations which are never true :
5.1 Solve : 12 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
5.2 Solve : y+1 = 0
Subtract 1 from both sides of the equation :
y = -1
One solution was found :
y = -1
Answer:
0 solutions
Step-by-step explanation:
These system of equations are inconsistent (parallel to each other) which means that there are no solutions to this system.
Answer:
3rd one
Step-by-step explanation:
Answer:
2.25
step-by-step explanation:
multiplying .95 times 45 and subtracting it by 45
Answer:
Multiply the bottom one by -4
Step-by-step explanation:
to cancel in a system of equations, there must be a negative and a positive of both variables. - times - equals +, so multiply -x by -4 to get 4x, thus cancelling -4x with 4x.
