x=2/9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−4−3x=6x−6
−4+−3x=6x+−6
−3x−4=6x−6
Step 2: Subtract 6x from both sides.
−3x−4−6x=6x−6−6x
−9x−4=−6
Step 3: Add 4 to both sides.
−9x−4+4=−6+4
−9x=−2
Step 4: Divide both sides by -9.
−9x
−9
=
−2
−9
The answer is: " 75 minutes " .

Answer:
No Solution
Step-by-step explanation:
Simplify 6−3 to 3.
5×3=6+3
Simplify 5×3 to 15.
15=6+3
Simplify 6+3 to 9.
15=9
Since 15=9 is false, there is no solution.

Answer:
(23/27, 11/9)
Step-by-step explanation:
Given the simultaneous equation;
-6x+5y=1..... 1
6x+4y=10.... 2
Add both equations
5y + 4y = 1+10
9y = 11
y = 11/9
Substitute y = 11/9 into 1;
From 1;
-6x+5y=1.
-6x + 5(11/9) = 1
-6x + 55/9 = 1
-6x = 1- 55/9
-6x = (9-55)/9
-6x = -46/9
x = -46/-54
x = 23/27
The solution to the system of equation is (23/27, 11/9)
