WebThe standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations. Sort by: Top Voted Questions Tips & Thanks Web3 (1-2x) = 4-6x First distribute the 3. 3*1 - 3*2x = 4-6x And multiply the terms. 3-6x = 4-6x Then add 6x to both sides. 3-6x+6x = 4-6x+6x The -6x+6x becomes zero. 3-0 = 4-0 And subtract the 0 from each sides. 3=4. 3 does not equal 4, so this is a false statement. This means the problems has no solution. imagic inventory software review
