Isolate the variable by dividing each side by factors that don't contain the variable.
y = 2 − x
Answer:
x=19
Step-by-step explanation:
Add 43 to both sides
14x-43+43=71+8x+43
simplify
6x=114
divide both sides by 6
6x/6=114/6
simplify
x=19
Answer:
7/53 or Alternative form 0.1296
Step-by-step explanation:
convert the mixed number to an improper fraction 2 with 7/10 turns to 27/10
reduce the number with greatest common divisor 3: 1/5*7/4 divided by 27/10
to divide by a fraction, multiply by the reciprocal of the fraction: 1/5*7/4*10/27
reduced the numbers with greatest common divisor 5: 7/4*2/27
reduced the numbers with the greatest common divisor 2: 7/2*1/27
multiply the fractions going side ways. 7/54
Answer:

Answer:
Third answer shown
Step-by-step explanation:
Since each equation has a right side equal to the same thing, y, those right sides must be equal to each other.
x + 3 = -2x + 6
Add 2x to both sides. 2x 2x
3x + 3 = 0 + 6
3x + 3 = 6
Subtract 3 on both sides. -3 -3
3x = 3
Divide both sides by 3. x = 1
Now, let's see what y must be if x equals 1.
Line M: y = x + 3 --> y = 1 + 3 --> y = 4
Line N: y = -2x +6 --> y = -2(1) +6 --> y = -2 + 6 --> y = 4, confirmed
So the ordered pair (x, y) that satisfies <u><em>both </em></u>equations is (1, 4)
*** This means that if you graphed both lines on an xy-coordinate plane, the point (1,4) would be the point where the two lines intersect.
That is the third answer shown.
