Answer:
Elimination
Step-by-step explanation:
A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Elimination is the best method when we have standard form equations and x values with opposite coefficients. This is so because the x variable will eliminate easily and allow us to solve for y.
S=4. if r=10 than it would be 3(10)= 10+5s.
30=10+5s
20=5s
s=4
720-100= 620
620- 120 = 500
500 - 112 = 388
388-128 = 260
260-133= 127
x=127
Answer:not true
Step-by-step explanation:
To say not true we need only one example so we can take x as -5
[-5]= [-5+1]
5 not equal with 4
