Answer:
x=32
Step-by-step explanation:
Arrange the equation in a manner that all variables are on the same side and all numbers with no variables are on the other side=
41+23=-6x+8x
64=2x
x=64/2
x=32
Answer:
90,105,75
Step-by-step explanation:
let the angle be x
so,
6x+7x+5x = 3×90
18x = 270
x= 270/18
x = 15
so the angles are , 6x = 90 , 7x = 105 , 5x = 75

Answer:
1 If the equations do not involve fractions or decimals, and you have a good visual understanding of linear equations, graphing on the coordinate plane is a good option.
2 Whenever one equation is already solved for a variable, substitution will be the quickest and easiest method.
3 Elimination is best used when both equations are in standard form (Ax + By = C). Elimination is also the best method to use if all of the variables have a coefficient other than 1.
