What does 15--13 equal 15 --13 equals 28 because a minus and a minus equals a plus so the equation is actually 15 plus 13 equals 28 p.s. i am only 10 years old?
Good work ! Did you have a question you wanted to ask ?
What equation is equivalent to y equals 2 over 3x plus 5?
3y = 2x + 15
The order pair for x plus y equals 15 and 4x plus 3y equals 38?
The solution pair is (-7, 22), demonstrated as follows: (1) x + y = 15 : given; (2)4x + 3y = 38 : given; (3)3x + 3y = 45 : equation (1), multiplied by 3; (4) x = -7 : equation (2), minus equation (3); (5) y = 22 : equation (1), minus equation (4).

What is the mistake in this solving of an equation 3x minus 12 equals 10x minus 15 minus 6x minus 10 3x minus 12 equals 4x minus 25 3x plus 13 equals 4x 13 equals x?
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?

Minus 15 divided by minus 3 equals?
12
3x plus 4y equals 90 4x-3y equals -5?
This is a simultaneous equation question. 4(3x+4y = 90) 3(4x-3y = -5) Multiply the top equation by 4 and the bottom equation by 3 then subtract the bottom equation from the top equation remembering that in maths a minus from a minus is equal to a plus. 12x+16y = 360 12x-9y = -15 And when subtracted: 0+25y = 375 Divide both sides of the equation by 25 to find the value of y: y = 15 Substitute 15 for y into the original equation to find the value of x: Solution: x = 10 and y = 15
