How do you do a two step equations?
example: 4x+5=13 First step: you must subtract 5 on each side. 4x=8 Second step: you must divide must side by four then it equals x=2
What are equations that have letters and fractions?
Equations that have letters are just called equations, but there are types 1, 2, 3, 4 and ratio type equations. Ratio type equations are the ones where it is a fraction on both sides of the equals sign. Equation (Type 2): x+1-5=12 Ratio Type Equation: 21/7=42-x/3
How do you check 2 step equations?
11k+7.7=15.4
What is the common point of these equations x equals 2 y equals 2x plus 1?
If X equals 2, then y = 5
What is the common point of these equations x plus 2y equals 6 x plus y equals 2?
When x = -2 then y = 4 which is the common point of intersection of the two equations.
What two step equation equals 29?
One out of many examples of two step equations that equal 29 is: (9 x 3) + 2
How do you find the solutions of the simultaneous equations of 2x plus 5y equals 16 and -5x-2y equals 2 showing work in step by step stages?
1 If: 2x+5y = 16 and -5x-2y = 2 2 Then: 2*(2x+5y =16) and 5*(-5x-2y = 2) is equvalent to the above equations 3 Thus: 4x+10y = 32 and -25x-10y = 10 4 Adding both equations: -21x = 42 or x = -2 5 Solutions by substitution: x = -2 and y = 4

What is a two step equations that equals 4?
From Nick, New York 2x/2=4
What is the common point of these equations x equals 2 y equals 2x plus 1?
If X equals 2, then y = 5
What is the common point of these equations x plus 2y equals 6 x plus y equals 2?
When x = -2 then y = 4 which is the common point of intersection of the two equations.
Will the matrix equations -18x plus y equals 8 and -3x-y equals -2 intersect?
-18 X + Y = 8 ........ 1 -3 X - Y = -2 ........ 2 Summing eq 1 and 2 - 21 X = 6 or X = - 6/21 or -2/7 Multiply eq 2 by 6 and subtract 2 from 1 7 Y = 20 or Y = 20/7 Accordingly, the two equations intersect at point: X = -2/7 and Y = 20/7
The equations of two lines are 6x-y equals 4 and y equals 4x plus 2. What is the value of x in the solution for this system of equations?
x=3
